INTRO TO COATING COMPOSITION 110

What is the definition of "solvent-borne coating"?

Conventional coating in which the main carrier is solvent. When exposed to normal temperatures, liquid solvents volatilize and release environmentally harmful volatile organic compounds into the atmosphere.

Also known as a resin, the mixture of ingredients that form the film that covers the surface of an object. Once applied, the binder cures into a uniform layer that holds together the coating's key components.

An agent that is applied to a surface and assists in adhesion between a surface treatment and the surface. In order for a resin to sufficiently adhere to a surface, sometimes the surface requires a chemical anchor.

Describes a process in which a material or object gains an electrical charge and consequently becomes attracted to another material or object with an opposite electrical charge. Flakes formed in powder coating are typically applied to a surface through an electrostatic process.

EPA. The governmental agency responsible for administrating laws to control and reduce pollution of air, water, and land systems. The EPA severely restricts the use of solvents in coatings, as solvents release VOCs.

The Environmental Protection Agency. The governmental agency responsible for administrating laws to control and reduce pollution of air, water, and land systems. The EPA severely restricts the use of solvents in coatings, as solvents release VOCs.

Also called a filler pigment, a pigment used primarily to reduce coating cost, while also enhancing coating performance. Filler pigments are often substituted for more expensive functional color pigments.

Also called an extender pigment, a pigment used primarily to reduce coating cost, while also enhancing coating performance. Filler pigments are often substituted for more expensive functional color pigments.

The ability of metallic flakes used in coating pigments to align themselves so that they are parallel with the surface. Metallic flakes used in leafing form provide a coating with strong weather resistance.

Also known as a binder, the mixture of ingredients that form the film that covers the surface of an object. Once applied, the resin cures into a uniform layer that holds together the coating's key components.

The substance that reduces the viscosity of the coating mixture enough to easily and efficiently apply the coating to a surface. Solvents assist in the application process, but immediately after application, are removed from the coating mixture, typically through evaporation.

Conventional coating in which the main carrier is solvent. When exposed to normal temperatures, liquid solvents volatilize and release environmentally harmful volatile organic compounds into the atmosphere.

A manufactured polymer that is often used a binder for coatings and is known for its strength and versatility. Urethane is made of isocyanate and alcohol, which are mixed together and undergo a chemical reaction to enable curing of a binder.

Volatile organic compound. A harmful gas or vapor released into the atmosphere when a liquid solvent volatilizes, or vaporizes. The EPA severely restricts the use of solvents as carriers for coatings, as solvents release VOCs.

VOC. A harmful gas or vapor released into the atmosphere when a liquid solvent volatilizes, or vaporizes. The EPA severely restricts the use of solvents as carriers for coatings, as solvents release VOCs.

The behavior of a liquid when the liquid contacts a solid surface. Liquids with poor wetting ability tend to form droplets, while liquids with good wetting ability tend to spread out evenly over the solid surface area.
